Raspberry Pi

After installing the RTL-SDR on my Clockwork uConsole (running a Raspberry Pi CM4) I was looking for something to try out the device to see what it could do. The GNU Radio Companion is still a bit baffling at the moment so I was searching for something with a lower barrier to entry.

One thing that caught my eye was a project on GitHub called dump1090. This is a "Mode S" decoder that uses the RTL-SDR to decode transponder information from Aircraft. Whilst the package is quite old now, it is still being minimally maintained. The dependencies are quite small and so it tends to compiles quite nicely without too many additional packages or issues, event on the limited hardware of the CM4.

I was scrolling through The Pi Hut website recently and my eye was drawn by a case for the Raspberry Pi Computer Module 4 (CM4) that looked like a modified Nintendo Gameboy. I had bought a CM4 for another project, but as that project wouldn't be delivered for a few months I was looking for something useful to do with the CM4 in the meantime.

The GPi Case 2 from Retroflag is a case that accepts the Raspberry Pi Compute Module 4 (CM4) and is used as an emulation station. Using the right software, it is possible to add files to the system that allow you to play games from a variety of different platforms. If you go for the WiFi CM4 you can also connect Bluetooth controllers to the unit and even use WiFi to transfer files.
